Configure interrupt sense based on device tree information. This extends
the OF interrupt map API to return sense information to the caller and
the PowerPC Open Firmware PCI base driver to use it to program the PIC.
Remove dead code. Most of this was in an #if 0 block; the rest is not
used and duplicates functionality in dev/ofw.
Simplify the ofw_bus_lookup_imap() API slightly: make it allocate maskbuf
internally instead of requiring the caller to allocate it.
Add vt support for RPi. (No early stage yet.)

Do not allow O_EXEC opens for fifo, return EINVAL.

Besides not making sense, open(O_EXEC) for fifo creates fifoinfo with
zero readers and writers counts, which causes premature free of pipes.

Require a C++11 compiler to build LLDB

In practice the old test (using MK_CLANG_IS_CC) is similar, but
COMPILER_FEATURES provides the information we actually want to test.

Do not create a hardware IPv6 server if the listen address is not
in6addr_any and is not in the CLIP table either.  This fixes a reported
TOE+IPv6 NULL-dereference panic in do_pass_open_rpl().

While here, stop creating hardware servers for any loopback address.
It's just a waste of server tids.
